Daily Hot Dog May Feed Diabetes Risk: Study08/10/11
WEDNESDAY, Aug. 10 (HealthDay News) -- Eating red meat --
especially processed products such as hot dogs -- increases your
risk of type 2 diabetes, a new study warns.
It also found that you can significantly lower your diabetes
risk by replacing red meat with healthier proteins, such as nuts,
whole grains or low-fat dairy products.
Harvard School of Public Health researchers looked at 20 years
of data from men in the Health Professionals Follow-Up Study, 28
years of data from women in the Nurses' Health Study I, and 14
years of data from women in the Nurses' Health Study II, which
involved more than 200,000 participants in all.
They combined that data with data from other studies that
involved a total of 442,101 people, including 28,228 who developed
diabetes while participating in a study.
After adjusting for lifestyle and dietary risk factors, the
researchers determined that a daily 100-gram serving (about the
size of a deck of cards) of unprocessed red meat was associated
with a 19 percent increased risk for type 2 diabetes.
A daily serving of 50 grams of processed meat -- equivalent to
one hot dog or sausage or two slices of bacon -- was associated
with a 51 percent increased risk of diabetes.
Among people who ate one daily serving of red meat, substituting
one serving of whole grains per day reduced the risk of diabetes by
23 percent. Substituting nuts resulted in a 21 percent lower risk,
and substituting a low-fat dairy product, a 17 percent lower
The study appears online Aug. 10 and in the October print issue
American Journal of Clinical Nutrition.
"Clearly, the results from this study have huge public health implications given the rising type 2 diabetes epidemic and increasing consumption of red meats worldwide," senior author Frank Hu, a professor of nutrition and epidemiology, said in a Harvard news release. "The good news is that such troubling risk factors can be offset by swapping red meat for a healthier protein."
Current U.S. guidelines that include red meats in the "protein
foods" group along with fish, nuts, beans and poultry should be
revised to distinguish red meat from the healthier protein sources,
the authors said in the release.
